United States Patent | 5,776,111 |
Tesio | July 7, 1998 |
A double catheter assembly is provided which includes two single lumen catheters that pass through the center portion of a stabilizer disk in a juxtaposed relationship. The stabilizer disk may be provided with holes in its periphery that facilitate suturing of the disk to a patient's skin at the insertion site, once the catheter is implanted. The portions of the catheters that are external to the insertion point are characterized by having a permanent bend proximate to the stabilizer disk that promotes patient compliance when the double catheter assembly is used in a catheterization.
